Background and pre-production On June 7, 1943, a film production titled
Chamber of Horrors was announced by
The Hollywood Reporter, noting that the cast would include
Boris Karloff,
Lon Chaney Jr.,
Bela Lugosi,
Peter Lorre,
Claude Rains,
George Zucco, and
James Barton with characters such as the Invisible Man,
the Mad Ghoul, the Mummy and "other assorted monsters".
Chamber of Horrors never went into production.
Curt Siodmak spoke little on developing the story for the film, stating that "the idea was to put all the horror characters into one picture. I only wrote the story. I didn't write the script. I never saw the picture". The screenplay was written by
Edward T. Lowe, who had previously written scripts for
The Hunchback of Notre Dame (1923) and
The Vampire Bat (1933). Lowe's script changed parts of Siodmak's story, including removing the mummy

Glenn Strange (right), in his Frankenstein's monster make-up The film's producer
Paul Malvern began assigning a cast that included Karloff, who Universal had on for a two-picture deal, Lon Chaney Jr.,
John Carradine and
J. Carrol Naish. The cast was officially assembled in February 1944. On discussions with the cast, Anne Gwynne confided later in an interview with Michael Fitzgerald that she did not think Karloff was happy with his mad scientist role in the film. In an interview in early 1944, Karloff stated he would "never play
Frankenstein's Monster again [...] Other people have taken similar roles and the edge is off of it. I am through with it.... I made these horror films. They were of little importance in anybody's scheme of things, including my own, and though I did make a disgraceful amount of money, I was getting nowhere." The role of the monster was given to
Glenn Strange, who over the previous 12 years spent his time in
Western films, Universal's ''
The Mummy's Tomb'' (1942), and
Producers Releasing Corporation's
The Mad Monster (1942) and
The Monster Maker (1944). Prior to Strange's casting,
Lane Chandler tested for the role. Strange was unaware that he was being called to play the monster and only found out when he was reported to
Jack Pierce's make-up studio to have a scar applied to him. After which, Pierce phoned producer Paul Malvern stating they had found their new monster.
Filming and post-production Preparations for
House of Frankenstein began in August 1943 under the title ''The Devil's Brood''. The film's budget was $354,000. This was the highest budget set for a Universal
Frankenstein film at that time, though
Frankenstein (1931) and
Bride of Frankenstein exceeded this amount by running over-budget. It was given a 30-day shooting schedule with initial shooting to begin on April 4, 1944, using the sets from
Green Hell (1940) and
Pittsburgh (1942). Other sets from
Gung Ho! (1943) and
Tower of London (1939) were also used. On set, Carradine treated those on set to recitations from the works of
Shakespeare and Chaney would occasionally prepare lavish lunches for his dressing room co-stars. Strange noted the monster make-up was uncomfortable on set, making him feel like he had
water on the brain and that he was not allowed into the studio commissary, having to eat a sack lunch away from others, leading Strange to speculate, "I guess they didn't want me to turn the stomachs of stars and starlets." The scene where Niemann thaws the monster's tissues with steam was accomplished by putting Strange in a glass case and pumping vapor into it. Long rubber hoses were put in Strange's nose so that he could breathe in spite of the vapor, but while shooting the scene Strange found he could not exhale efficiently through the hoses and was suffocating, prompting him to frantically push a
panic button which the prop crew had installed inside the case. Strange also had a scene where he throws J. Carrol Naish through a window and onto prop mattresses. Strange misjudged his throw, leading to Naish missing the mattress and landing on the cement floor. Naish's large padded hunchback cushioned his fall sufficiently to prevent serious injury. Blonde-haired
Elena Verdugo wore a brunette wig for her part, since the studio would not accept a blonde gypsy. She choreographed Ilonka's gypsy dance herself, and had to make it work around the rocks which littered the filming location. Director
Erle C. Kenton set the scenes involving Count Dracula to be shot last. Filming was completed on May 8. The music score was a collaborative effort between
Hans J. Salter,
Paul Dessau and
Charles Previn. Most of the film's score was written specifically for
House of Frankenstein, as opposed other films of the period that re-used older musical cues. After filming was completed in May and prior to its premiere, the film's title was changed to
House of Frankenstein. ==Release==
